During a two hour session, the music therapist helps the patient express her own thoughts about what she's been going through. Those thoughts then become lyrics to an original composition.

"They get to pick and choose," says Sandheinrich. "Do they want their song to be fast or slow? Rock and Roll? Or country sounding?"

Arianna decided that the name of her song should be, "You Can Get Through It."

What does Arianna want people to know about this?

"That they can get through (cancer)," she says.

After writing the song, they sing and record it. When lyrics come from the heart, they often touch yours. And when the session is over, Arianna gets a CD to take home and play anytime she wants.

"The song is about helping other people," says Zucker. "And I'm really proud of her for being able to share what she knows."

"I'm going to think about the song, "Arianna says. "And other kids who have cancer."

No one knows what tomorrow will bring, but clearly today brought joy and accomplishment for Arianna. Kids Rock Cancer is providing a great escape and a sense of harmony, a treatment that's hitting all the right notes.
